50 MHz Cortex-M4 with single-cycle multiply-accumulate and hardware divide. 128 KB Flash and 16 KB SRAM fit a single control loop with USB stack or a modest RTOS.
Rated -40 to 105°C. 32-QFN-EP (5×5 mm) package with exposed pad requires thermal vias. Supply range 1.71 to 3.6 V.
The MK20DX128VFM5 operates at a maximum clock frequency of 50 MHz.
Yes, the MK20DX128VFM5 includes a USB OTG controller, allowing it to operate as either a USB host or device without an external PHY.
The pin-compatible MK20DX128VLH5 (64-LQFP) is a valid alternate within the same Kinetis K20 family, sharing the same core, memory, and peripheral map but in a larger package with more I/O.
The MK20DX128VLH5 is the 64-LQFP variant of the same die; it offers more I/O pins (up to 40) versus the 20 I/O on the 32-QFN MK20DX128VFM5, at the cost of a larger footprint (10×10 mm vs 5×5 mm).
